| 2 |
|

| 3 | This is both an example of how WSGI can be implemented, and a basis for running
|
|---|
| 4 | simple web applications on a local machine, such as might be done when testing
|
|---|
| 5 | or debugging an application. It has not been reviewed for security issues,
|
|---|
| 6 | however, and we strongly recommend that you use a "real" web server for
|
|---|
| 7 | production use.
|
|---|
| 8 |
|
|---|
| 9 | For example usage, see the 'if __name__=="__main__"' block at the end of the
|
|---|
| 10 | module. See also the BaseHTTPServer module docs for other API information.
